SPECIFICATION forming part of Letters Patent No. 362,797, dated May 10,1887. Application filed December 16, 1886. Serial No. 221,777. I (Nomodel.)

To all whom it may concern.-

Be it known that I, GEORGE W. THOMSON, a citizen of the UnitedStates,residing at Grove City, in the county of Mercer and State ofPennsylvania, have invented certain new and useful Improvements inMotors; and I do hereby declare the following to be a full, clear, andexact description of the same, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawing, and to the letters and figures of referencemarked thereon,which form a part ofthis specification.

My invention relates to improvements in mechanical motors, especiallyadapted for operating churns and washing-machines; and it consists incertain novel features, hereinafter described, and particularly pointedout in the claim.

In the annexed drawing I have shown a side view of my device, the framebeing in section and the moving parts in elevation.

Referring to the drawing by letter, A designates the frame, consistingof four posts or standards connected by braces a, as shown. Thestandards are arranged in pairs, and through the upper ends of the frontpair of standards I insert a pin, 1), upon which is pivotally mountedthe lever B. The pivot-pin 1) passes through the central point of thelever B, and depending from the said lever is a pendnlum, 0, having aweight, D, secured to its lower end.

E E are braces, which have their opposite ends connected, respectively,to the lower end of the pendulum O and the ends of the lever B. It willbe seen that one of these braces is entirely within the frame of themachine, while the other one is outside or beyond the end thereof. Tothis latter brace I secure a bar, F, in such manner as to leave a spacebe tween the said bar and the brace.

G is an arm secured at its inner end to the pendulum O, and passingthrough the said space between the brace E and bar F. This arm G is usedwhen it is desired to operate the device by a horizontalstroke.

J is a pitman adjustably secured to the lever B, near the rear end ofthe same, and extending down to near the base of the machine, where itis connected to a treadle, L, working in an open space, K, between therear standards of the frame.

I designates a guide-frame secured to the rear end of thesupporting-frame, and having a slot, t, at its upper end, in which therear end of the lever B works. In the ends of this slot 2', I secure thebuffers or cushions i, which can be adjusted to regulate the stroke ofthe lever, as will be readily understood.

H is a pitman for connecting the front end of the lever B to thedasher-shaft of a churn, or the agitatorshaft of a washing-machine.

The operation of the device is simple and will be readily understood.The treadle L is operated by the foot in the usual manner, and themotion of the same is communicated to the pitman H through the pitman Jand the lever B. The pendulum 0 acts as a governor, to make theoperation of the machine easy, regular, and smooth.

Having thus described my invention, what I claim and desire to secure byLetters Patent, 1s

The hereindescribed motor, comprising a main frame, A, a verticalguide-frame, I, at" fixed to one end of the main frame, and having alongitudinal slot, the elastic cushionblocks fitted in opposite ends ofthe slot of the guideframe, one of said cushion-blocks being adjustablein the slot toward and from the other block, an oscillating lever, B,pivoted centrally in the other end of the main frame, and having one endthereof working in the slot of the guideframe, and adapted toalternately come in contact with the cushionblocks, which thereby limitthe play of the said lever, a Weighted pendulu nrgovernor suspendedcentrally from the oscillating lever,and having the inclined bracesconnected thereto, and a treadle connected by an intermediate pitmanwith the oscillating lever B, the free end of the said lever beingadapted to be connected with the churn or other device to be driven bythe motor, as and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand inthe presence of the subscribing witnesses.

GEORGE XV. THOMSON.
